G-Helper vs MemTest86

G-Helper is a free, portable Windows control tool for Asus laptops and handhelds. It brings together performance, fan, GPU, battery, and RGB controls in a single executable that does not require installation. Performance modes are Silent, Balanced, and Turbo, with built-in fan curves; GPU modes are Eco, Standard, Ultimate, and Optimized. Dedicated GPU controls include core and memory clock offsets, GPU power, Dynamic Boost, and temperature limits. Automation can change performance mode, GPU mode, screen refresh rate, and keyboard-backlight timeout according to AC or battery power. An in-game overlay reports FPS, CPU and GPU temperatures, fan RPM, and power draw. Selected Asus mice, keyboards, and headsets can have lighting, bindings, equalizers, and battery settings. The app checks Asus for model-specific BIOS and driver updates and uses the Asus System Control Interface driver plus BIOS-stored operating modes. It requires the .NET 10 Desktop Runtime and that Asus driver. The desktop application says it does not collect or transmit personal data.

MemTest86 is a bootable utility that checks computer RAM for faults using memory test algorithms and patterns. It runs from a USB drive without an installed operating system, although Windows, Linux, or an Intel-based Mac can be used to create that drive. Version 11.7 requires UEFI firmware and x86 or ARM64 hardware, and does not support Apple Silicon M-series Macs. Its listed coverage includes 14 algorithms, such as SIMD, Row Hammer, and DMA tests, and support for DDR2, DDR3, LPDDR4, LPDDR5(x), ECC, CDIMM, and CAMM2 memory. It can create customizable HTML reports and, on supported configurations, decode an error address to identify a failed DIMM or chip. The Free Edition supports up to 16 CPU cores; Pro supports up to 512 and adds automation and custom tests. Site Edition adds PXE-based LAN deployment and Management Console integration. The Free Edition costs nothing; Pro Download costs $116, paid once.
